Description
Technical field
The present invention relates to a kind of static mixer, relate in particular to a kind of helical static mixer for the high-viscosity material mixing.
Background technology
Static mixer is that all kinds of fixing elements are installed in a kind of utilization in pipeline, thereby the flow regime of utilizing these elements to change the flowing pipe inner fluid reaches a kind of blender that liquid mixes purpose, and the static mixer of this no-rotary part and channelization characteristics is used obtaining aspect the commercial Application more and more widely with its novel, efficient and energy-conservation superiority.
At present on the domestic and international market successful release multiple static mixer, be widely applied industrial, wherein representative static mixer mainly contains following several: Suhl scholar (Sulzer) SMV type, toray Hi type and the Ross-ISG type of the Kai Nisi of the U.S. (Kenics) type, Switzerland.Because the internal mixer architectural difference of these kinds, the mixing principle of all kinds static mixer is different, and the mixed characteristic difference is larger, and then mixed effect is also different.Aspect mixed effect in the reasonable static mixer take the Suhl scholar's of Switzerland S-X type static mixer as representative, the primary structure of the static mixer of this brand is with the mutual electric welding of blade and linear array, 45 degree that oppositely intersect are rear in linear array, interlaced one-tenth 90 degree in two groups of blades, after high-viscosity material enters the S-X static mixer, and after the repeatedly cutting of blade, reach the effect of mixing.But the S-X static mixer causes the PVAc pump discharge pressure of blender leading portion to increase because flow resistance is excessive, damages the situation of PVAc pump, also result in blockage easily simultaneously, because S-X static mixer internal structure is too complicated, in use, cleaning frequency is short, troublesome poeration.
Summary of the invention
The technical assignment of technical problem to be solved by this invention and proposition is that prior art is improved, and a kind of helical static mixer is provided, and flow resistance Da Yi stops up when solving present technology medium-high viscosity mixing of materials, the problem that mixing efficiency is low.
For solving above technical problem, technical scheme of the present invention is:
A kind of helical static mixer, comprise shell, mounting flange, left-handed blade and dextrorotation blade, it is characterized in that, it is cylindric that shell is, two ends at shell all are provided with respectively mounting flange, and left-handed blade and dextrorotation blade are many helical-blades structure, and left-handed blade and dextrorotation blade are placed on enclosure, from the entrance of shell to exporting successively alternative arrangement, and adjacent left-handed blade and dextrorotation blade are fixedly connected with at circumferential stagger angle.When passing through blender, in pipeline, impacts fluid left-handed blade and dextrorotation blade, be divided into a plurality of fluids by helical blade, and because the streamlined structure of helical blade has been alleviated the impulsive force of fluid, fluid flows along helical blade, flow resistance is less, the difficult obstruction, also increase simultaneously the velocity gradient of fluid laminar motion or form turbulent flow, " cutting apart-position movement-again converge " during laminar flow, during turbulent flow, fluid is except appealing three kinds of situations, also can produce violent eddy current in the section direction, have very strong shearing force to act on fluid, make fluid further cut apart mixing, fluid is constantly cut by helical blade in blender like this, shear, rotation and again mixing finally form needed emulsion.
Further, described left-handed blade and dextrorotation blade are taken to the structure of rare double helix leaf intersection twist type.Intersecting the helical-blade quantity of twist can be with increase in demand, and the flow resistance of double helix leaf is minimum, and the flow resistance of multi-head spiral impeller structure can become larger but mixed effect is better, requires to select the helical-blade structure of varying number according to fluid-mixing self-characteristic and degree of mixing.
Further, the windup-degree of the single helical blade of described left-handed blade and dextrorotation blade is 90 ° ~ 360 °.The turbulent flow that the larger fluid impact blade of the windup-degree of single helical blade forms is also just stronger, the mixed effect of fluid is also just better, but flow resistance is just larger when the windup-degree of helical blade is larger, rate of flow of fluid reduces, and need to require to select different helical blade windup-degrees according to fluid-mixing self-characteristic and degree of mixing equally.
Further, the draw ratio of described left-handed blade and dextrorotation blade be 1:1 to 2.1:1, formulate according to the windup-degree of helical blade, guarantee the structural strength of monomer helical blade, adjust the size of flow resistance.
Further, described left-handed blade is 30 ° ~ 90 ° at the circumferential stagger angle with dextrorotation blade junction.The staggered certain angle of adjacent left-handed blade and dextrorotation blade can further be cut apart and converge by convection cell, promotes the mixing of fluid.Different stagger angles is fit to the mixing of inhomogeneity material, and stagger angle is decided with the working condition requirement of reality.
Further, alignment pin is adopted in the junction of described left-handed blade and dextrorotation blade, is fixed with spot welding or the mode that is threaded, has increased greatly the bonding strength between helical blade, guarantee not fracture under the impact of fluid again of junction, increase the service life of blender.
Further, one end of the vane group that described left-handed blade and dextrorotation blade form is connected with the cleaning suspension ring, vane group integral body can be pulled out from the blender shell, clean, assembly and disassembly is convenient, and can clean up any dead angle of vane group, prevent residual flow-induced corrosion helical blade.
Further, an end of described shell is equipped with in order to the installation locating slot that the blade string is fixed, and makes things convenient for the installation of helical blade set, prevents that helical blade set is in the living frictional dissipation of housing inward turning forwarding.
Compared with prior art, the invention has the advantages that:
Helical static mixer of the present invention overcomes the deficiencies in the prior art, greatly reduced flow resistance, when mixing high-viscosity material, be difficult for stopping up, guaranteed simultaneously the effect of mixing, one independently blade unit material is repeatedly cut, in the blender sleeve pipe, adopted the form of multistage blade unit, cutting apart and converging of material is effective, mixing efficiency is high, and energy efficient greatly; The fluid treatment amount is large, and dependable performance in the larger situation of mass flow, all can realize continuously, mix fast and efficiently, adopts different helical blade structures for the requirement of different material self-characteristics and degree of mixing, and applicability is strong; And simple in structure, easily assembling, easily manufactured, save production cost, move simple and reliablely, be convenient to clean.
